24bit without 30bit color(HDR) - 29Gbps, HDR (4:4:4 - lossless color depth) - 36Gbps.
LG declared FreeSync Premium Pro - it's have 4:4:4 mode for HDR...
If there is a decent review with a real flow check, everything will immediately become clear. In principle, DP/HDMI operating mode analyzers are already on the market, even for the latest standards. It's strange that the editors haven't purchased them for reviews yet. It is enough to plug such a device into the port and check in what mode the monitor requests the signal.
Well, or check this programmatically with a specialized program, if you have a computer with a full version of the required port.
I saw a sign from several of the latest monitors with QD/W-OLED, where so far only Gigabyte has found a DP2.0+/UHBR20 input port for 4k@240Hz. The funny thing is that there is not a single video card and not a single port on a laptop that supports this monitor today, as far as I know. Where will buyers connect it?
